Serializers for java.time.*

[rrva]

What is your use-case and why do you need this feature?

We use a lot of java.time.OffsetDateTime which it is a bit cumbersome to have to annotate separately with a custom serializer like @Serializable(KOffsetDateTimeSerializer::class).

Describe the solution you'd like

It would be useful to have a special org.jetbrains.kotlinx:kotlinx-serialization-jvmtime dependency which automatically adds serializers to handle some very common classes from the java8 java.time module.

Currently, it is possible only with @file:UseSerializers annotation. For module-wide options / auto-including from dependency, there is a separate issue: #507
